Mounting unit for a window or a door

ABSTRACT

A mounting unit for a window or a door including a frame and a leaf mounted on the frame. The leaf is movable from a closed position by at least one curved guiding mechanism into a parallel knockout position and the leaf is pivotable from the parallel knockout position about a vertical axis into a rotary opening position. At least one upper horizontal guiding mechanism is provided on a top side of the leaf and at least one lower horizontal guiding mechanism is provided on a bottom side of the leaf to guide the leaf. In a closed position of the leaf, the at least one upper and the at least one lower horizontal guiding mechanisms are arranged inside the frame. The at least one upper and the at least one lower guiding mechanisms are each linked about the vertical axis to the frame and the leaf.

BACKGROUND

The present disclosure relates to a mounting unit for a window or adoor. The mounting unit includes a frame on which a leaf is held. Theleaf is movable from a closed position by at least one curved guidingmechanism into a parallel knockout position. The leaf is pivotable fromthe parallel knockout position about a vertical axis into a rotaryopening position.

From German Patent Document DE 10113597, a mounting unit for a window ora door is known, in which a leaf can first be moved into a knockoutposition in order to then be pivoted from this knockout position into arotary opening position. For the parallel knockout of the leaf,connecting link guides are provided, while the pivoting takes placeabout a vertical axis which can be moved horizontally by the length ofthe knockout movement. This mounting unit is arranged such that, as aresult of the fixed distance of the leaf from the axis of rotation atthe frame, the leaf cannot be opened completely, that is, only at 90°.The opening angle can be slightly enlarged by corresponding contours ofthe frame and of the leaf which, however, does not reach the goal of theopening by 90° and additionally is visually a problem.

Furthermore, it had been suggested in the prior art to, on the one hand,permit a knockout of a window and, on the other hand, permit a rotaryopening only from the closed position. However, this construction ispoorly suitable for an automatic opening operation because two possibletypes of movements are available which first require a selection.

A mounting for a tilting-pivoting leaf with a scissors-type knockoutarrangement is also known from German Patent Document DE 1 086 147. Byuse of the mounting, the window can optionally be brought into a tiltingor rotary opening position.

Furthermore, a parallel knockout window with a rotary function is knownfrom German Patent Document DE 19825071, in which a mounting elementreaches angularly around a frame, a connecting link guide for theparallel knockout of the window being provided at the mounting elementitself. These mounting elements are mounted on the frame from theoutside and are therefore visually conspicuous. On the other hand, themounting elements have to be guided through the sealing devices betweenthe leaf and the frame. In addition, the mounting element itself acts asa cold bridge. This construction is not suitable for high-quality doorsor windows.

SUMMARY

The present disclosure relates to a mounting unit for a window or a doorwhich permits a parallel knockout and a pivoting into a rotary openingposition with a large opening angle in a compact construction.

The present disclosure includes a mounting unit for a window or a door,The mounting includes a frame and a leaf mounted on the frame. The leafis movable from a closed position by at least one curved guidingmechanism into a parallel knockout position. The leaf is also pivotablefrom the parallel knockout position about a vertical axis into a rotaryopening position. At least one upper horizontal guiding mechanism isprovided on a top side of the leaf and at least one lower horizontalguiding mechanism is provided on a bottom side of the leaf. The at leastone upper and the at least one lower horizontal guiding mechanisms areconfigured to guide the leaf. In a closed position of the leaf, the atleast one upper and the at least one lower horizontal guiding mechanismsare arranged inside the frame. The at least one upper and the at leastone lower guiding mechanisms are each linked about the vertical axis tothe frame and the leaf is rotatably held on a pin spaced-apart from atleast one of the at least one upper and lower horizontal guidingmechanisms.

According to the present disclosure, the leaf is held on a frame forguiding the leaf and at least one upper horizontal guiding mechanism isprovided on a top side of the leaf and at least one lower horizontalguiding mechanism is provided on an underside of the leaf. The at leastone upper and lower horizontal guiding mechanisms are arranged insidethe frame in the closed position of the leaf. As a result, no mountingparts protrude beyond the leaf or the frame in the closed position.Therefore, a good heat insulation and a compact construction areachieved. Furthermore, as a result of the horizontal guiding mechanisms,a stable guidance of the leaf is achieved which can be moved into arotary opening position with a large opening angle. The term “pivoting”comprises any rotational movement, in which case another relativemovement of the leaf with respect to the axis of rotation may exist.

The upper and the lower guiding mechanisms are each linked to the frameabout a vertical axis, so that the corresponding mounting parts can bemounted on an interior side of the frame. The upper guiding mechanismthen extends at least partially along the top side of the leaf, and thelower guiding mechanism extends at least partially along the undersideof the leaf, so that the guiding mechanisms are not visible in theclosed position and appear only during the pushing-out and pivoting ofthe leaf.

According to an embodiment of the present disclosure, a vertical axispasses through a space between the frame and the leaf. It will then beable for the leaf to move away relative to the vertical axis during thepivoting in the opening direction, so that, during the pivoting, theleaf does not strike against the frame and a maximal opening position islimited.

In order to move the leaf slightly away from the axis of rotation duringthe pivoting, an additional guiding mechanism can be guided on the frameat least on the upper side. The additional guiding mechanism isconnected with the other guiding mechanism in a hinged manner. The leafcan be at least partially held on the additional guiding mechanism, sothat a defined pivoting movement takes place during the opening. In thiscase, the additional guiding mechanism is guided with one end on theframe and is linked to the guiding mechanism on the opposite side. Alinking of the guiding mechanism is provided between a fastening pointfor the leaf and the guidance in the frame. The distance between thelinkage of the guiding mechanism and the fastening point for the leafcan be utilized for removing the leaf during the pivoting in the openingdirection from the axis of rotation of the guiding mechanism. Thus, alarger maximal opening position can be achieved than would be possiblewithout a corresponding radial movement.

In order to avoid damage caused by an excessive opening of the leaf, anopening limit is provided. As a result, the mounting unit is alsosuitable for an automatic operation. The opening limit has two armswhich are hinged to one another and whose pivoting capacity relative toone another is limited by a stop. As a result, the opening limit can bemounted on a relatively small space. As an alternative, the displacementof an additional guiding mechanism can be selected as an opening limit,which would then require slightly more space.

According to another embodiment of the present disclosure, a leaf lifteris mounted in the area of the axis of rotation of the lower guidingmechanism on the frame in order to introduce the weight of the leaf intothe frame. For this purpose, the leaf lifter may have an angularconstruction and by a leg reach under the leaf, a stable supportingtakes place. A second leg can be fastened laterally to the leaf. In thiscase, a certain elasticity will then exist so that the knockout movementof the leaf is compensated by a warping of the upper leg. In this case,the leaf lifter can also be slightly tipped laterally so that the leafis always securely held even during an adjusting movement of the leaves.

Further, to obtain a compact construction, corner deflections can beprovided on the side of the leaf situated opposite the vertical axis, onwhich corner deflections one radial cam respectively is mounted for theparallel pushing-out of the leaf.

Other aspects of the present disclosure will become apparent from thefollowing descriptions when considered in conjunction with theaccompanying drawings.

DETAILED DESCRIPTION

A mounting unit is mounted on a frame 1 having a leaf 2. The leaf 2 ismovable from the frame 1 first into a parallel moved-out position andthen into a rotary opening position. The leaf 2 can be pivoted about avertical axis 3.

A handle 5, which moves a connecting rod mounting 6 via a gearing 4, isprovided for moving the leaf 2. The connecting rod mounting 6 isconnected with an upper and a lower curved guiding mechanism 8 viacorner deflections 7. Adjacent to the curve guiding mechanism 8, anotherconnecting rod mounting 9 is provided which is connected with a curvedguiding mechanism 10 in order to ensure a parallel pushing-out of theleaf 2 in an area of the axis 3 of rotation.

In the closed position of the leaf 2, the handle 5 is oriented downward.A maximal parallel knockout position of the leaf 2 is reached during apivoting of the handle 5 in an upward position via a horizontal positioninto a diagonal position just before a perpendicular position. If thehandle 5 is rotated still farther into the upward-oriented position, theleaf 2 is released at the curve guiding mechanisms 8 and can thus bepivoted about the vertical axis 3. For this purpose, an upper knockoutdevice 11 and a lower knockout device 12 are provided, which are furtherexplained herein.

FIGS. 2A and 2B show the curved guiding mechanism 8. The curved guidingmechanism 8 comprises a basic body 13 in which a groove-shaped radialcam 14 is recessed. The basic body 13 is fastened to the leaf 2 viascrews 15 and is mounted on a connecting rod mounting 9 or on the cornerdeflection 7. A pin 16 is fastened on the frame 1. It is alsoconceivable to connect the pin 16 with the connecting rod mounting 9 orthe corner deflection 7 of the leaf 2 and to mount the basic body 13 onthe frame 1.

The pin 16 moves in the radial cam 14 and is arranged in the lowerposition when the leaf 2 is closed. When the pin is moved into position16′, the leaf 2 is in the maximally pushed-out position. In thisposition, the pin 16′ is arranged at a mouth 17 and can leave the curveguiding mechanism 8. In position 16″, the pin is situated outside thebasic body 13, and the leaf 2 is in a rotary opening position.

FIG. 3 is a top view of an upper area of the mounting unit of FIG. 1.For guiding the leaf 2, a guiding mechanism 20 is provided which can berotated about vertical axis 3. For a better overview, the frame 1 isillustrated to be slightly removed from the leaf 2. A web 18 rests onthe leaf 2 and, on an opposite interior side, a sealing device 19 on theleaf 2 rests on the frame 1. On the opposite side, the guiding mechanism20 is connected via an oblong hole with a bolt 25 which is disposed in ahousing 50 illustrated in FIG. 9. The housing 50 itself is anchored in apositionally fixed manner in a mounting receiving groove of the leaf 2.

An auxiliary guiding mechanism 24 is mounted on the guiding mechanism 20at pin 26 and, at an axis or pin 27, is hinged to an additional guidingmechanism 21. The additional guiding mechanism 21 is also linked via anaxis or pin 28 to the housing 50 and is connected with the leaf 2. On anopposite side, a slide 22 is provided on the additional guidingmechanism 21, which slide 22 is movably disposed in a groove 23 on theframe 1.

For a parallel moving-out of the leaf 2, the leaf 2 is lifted off theframe 1 via the curve guiding mechanisms 8, 10 of the leaves 2, so thatthe leaf 2 reaches position 2′. In this position, the guiding mechanism20 is in position 20′ and the additional guiding mechanism 21 is inposition 21′. The leaf 2′ is held on the axis or pin 28 via the curvedguiding mechanism 10 as well as by fastening devices. During movementfrom a closed position into an opened pivoting position 2″, the leaf 2moves away relative to the axis 3 of rotation. The reason is that theleaf 2 is not mounted directly on the guiding mechanism 20 but on theaxis or pin 28 of the additional guiding mechanism 21.

In the closed position, a distance A exists between the axis or pin 28and the axis 3 of rotation, and a distance equal to a exists betweenaxis or pin 27 and axis or pin 28. In the opened position, the axis orpin position 27″ is situated closer to the axis or pin 3 of rotationthan the axis or pin 28″, the radial distance between the axes 27″ and28″ amounting to b. The distance between the axis 3 of rotation and theaxis 28″ is marked as B. The following geometrical relationship isobtained on the basis of the linkage of the guiding mechanisms: B=A+a+b.

In other words, during a pivoting, the leaf 2 is moved by the length a+bfarther away from the axis 3 of rotation. The leaf 2 is prevented fromresting via sealing device 19 or a corresponding contact edge againstthe frame 1 and the maximal opening position is limited. In theillustrated embodiment of FIG. 3, the maximal opening position isreached when, in position 22″, the slide 22 rests against a stop andtherefore no further pivoting movement of the leaf 2 can be carried out.

In an alternative embodiment illustrated in FIG. 4 for an upper knockoutdevice 11 (see FIG. 5A) in the area of the axis 3 of rotation, anauxiliary guiding mechanism 24, as shown in FIG. 3, is omitted. Aguiding mechanism 20 is disposed on an axis or pin 3 of rotation fixedto the frame 1 and is connected with an additional guiding mechanism 21via axis or pin 29. The additional guiding mechanism 21 is situatedabove a slide 22 which is held in a groove (see axis 23) on the frame 1.Furthermore, axis or pin 28 is provided on the additional guidingmechanism 21, on which axis the leaf 2 is disposed via housing 50. Inaddition, the leaf 2 is also disposed on a curved guiding mechanism notshown, on the guiding mechanism 20.

For an opening of the leaf 2, the leaf 2 is first moved into parallelpushed-out position 2′. Subsequently, the leaf 2 is opened and pivotedinto position 2″, the slide 22 being moved into the opening position 22″to a stop. The additional guiding mechanism 21 moves to position 21″,then projects diagonally and holds the leaf 2″ on the axis or pin 28″.

FIG. 5A shows the knockout device 11 according to FIG. 4, but viewed ona plane of the leaf 2. The guiding mechanism 20 is fastened to the axis3 of rotation and is connected with an additional guiding mechanism 30via axis or pin 28, which additional guiding mechanism 30 is used as apivot limiting device. The leaf 2 is held on the additional guidingmechanism 30 on an axis or pin 29. Furthermore, a pin 91 is provided onthe guiding mechanism 20, which pin 91 engages in a radial cam 90 ofcurved guiding mechanism 10 which is displaceably disposed on the leaf2. In contrast to the curved guiding mechanism 8 of FIG. 2A arranged onthe side of the handle 5, the radial cam 90 has a closed design and onlypermits the pin 91 to carry out a sliding motion. The shape of theradial cam 90 is illustrated in FIG. 6A.

FIG. 7 shows an upper part of the mounting unit of FIG. 5A, similar toFIG. 6A, but in a maximally parallel moved-out position of the leaf 2.The pin 91 has moved in the radial cam 90, and the leaf 2 has movedcorrespondingly. For reasons of clarity, the connecting rod 9 isillustrated at a distance from the curve guiding mechanism 10.

FIG. 8 shows the knockout device 12 in a lower area of the leaf 2. Thecurved guiding mechanism 10 was moved via stationary control pin 91 andthereby caused the parallel pushing-out of the leaf 2.

FIG. 9 shows the leaf 2 in the opened position. In this embodiment, theillustrated knockout device is arranged at a top side on the leaf 2 but,can also be mounted on a bottom side. The guiding mechanism 20″ isconnected via axis or pin 29″ with an additional guiding mechanism 30which also has the effect of a limit for the pivoting-out motion. Forthis purpose, the additional guiding mechanism 30 has a two-partconstruction including a first lever 31 and a second lever 32 which aremutually connected via axis or pin 33, the pin 33 being held in anoblong hole 34 of the lever 31. The lever 31 is rotatably fixed on a pin36 on the frame 1. On the lever 32, the guiding mechanism 20″ is fixedto the pin 29″, while the leaf is held on a pin 28″.

The opening position of the leaf 2 is limited in that a stop 35 ismolded to the lever 31, which stop 35 permits a maximal angle of thelevers 31 and 32 of less than 180°. As a result, the leaf 2 cannot jameven in an automatic operation. For closing the leaf 2, the two levers31 and 32 are folded over one another, so that the space requirement forthe additional guiding mechanism 30 and the limit for the pivoting-outmotion is kept comparatively low.

FIG. 10 illustrates a lower knockout device 12 in a view on a plane ofthe leaf 2. In the area of the axis 3 of rotation, a leaf lifter 60 isprovided which, via a first horizontal leg 41 of the leaf lifter 60,reaches under the leaf 2 and, via a second leg 42 of the leaf lifter 60,is laterally fixed to the leaf 2. The horizontal leg 41 corresponds toguiding mechanism 20. For this purpose, second or upper leg 42 isfastened via pin 43 to an adjusting mounting 44 on the leaf 2.

The leaf lifter 60 is fastened on the frame 1 via pin 40 which forms theaxis 3 of rotation. In the area of the axis 3 of rotation, a bearingdisk 45 is provided below the leaf lifter 60, so that a weight of theleaf 2 can be carried off to the frame 1.

The leaf lifter 60 has no pivot about a horizontal axis. But, as aresult of the lower leg 41, which also acts as a guiding mechanism, awarping of the leg 41 takes place which is supported on the bearing disk45 by its edges during the parallel moving-out of the leaf 2 and, in theprocess, compensates for a measurement component which is the result ofthe tilting of the leaf lifter 60 during the parallel moving-out. Inaddition, starting from the adjusting mounting 44, the leaf lifter 60 isshaped and constructed diagonally downward to the frame 1 in order tointroduce the weight of the leaf 2 into a frame corner. A length of theleaf lifter 60 is selected to be relatively large because this leaflifter 60 has to compensate a lifting-off movement of the leaf 2 fromthe frame 1 during the rotary opening by a deformation.

In the preceding embodiments, guiding mechanism 20 was illustrated inwhich at least one additional guiding mechanism 21, 30 is mounted. Thatwas in order to dispose the leaf 2 on the additional guiding mechanism21, 30 and thereby achieve a relative movement away from the axis 3 ofrotation of the guiding mechanism 20 during the pivoting of the leaf 2out of the pushed-out position. This additional guiding mechanism 21, 30is stable and can easily be placed in a space between the leaf 2 and theframe 1, so that it is not visible from the outside. However, it is alsoconceivable that, instead of the illustrated additional guidingmechanisms 21, 30, other mechanisms can be used which permit a pivotingof the leaf from the pushed-out position.
